TECHNICAL CORNER

IMPRESSED CURRENT VS. GALVANIC ANODE CP SYSTEMS

The following are considerations when selecting the type of cathodic protection (CP) system for a newly installed, existing buried or submerged structure.

Surface Area of Exposed Metal

The size and cost of most CP systems are controlled by how much CP current is required to effectively protect the exposed metal in contact with the electrolyte (soil or water). Therefore, one of the first considerations when designing or selecting a CP system is the surface area of metal exposed to the electrolyte.

A bare or uncoated structure will require an amount of CP current proportional to the surface area of metal exposed to the electrolyte. Most modern pipelines, as well as other structures, are provided with a coating system. The coating system is intended to isolate the steel physically and electrically from the electrolyte. Therefore, if the structure is completely and properly coated, it would be isolated from the soil and no CP would be required. Theoretically, this is correct. However, it is extremely rare that a structure could be buried or submerged without some minor damage or imperfections to the coating system. Referred to as coating “holidays,” these imperfections result in small areas of the structure metal being in contact with the electrolyte, and where these coating holidays exist, the metal will be vulnerable to corrosion.
